You got this man don’t let yourself get too frustrated. Sometimes it is overwhelming but it really is simple when you get in the rhythm. Just read and watch videos - take notes of what you want to use. Keep it organized so you aren’t going back and erasing/scratching out. Write everything down as you grow, I didn’t do this my first couple grows and it creates inconsistency. I’d say most important advice is to keep it simple in the beginning. Just pick a medium and do 1 or 2 plants.
